Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern repeats uniformly around the outer circumference and shoulder of the tire, the opposite side perspective view being identical thereto; and,

FIG. 2 is a frontal elevational view thereof.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown along the top and bottom edge of FIG. 2.

The broken line disclosure of the tire sidewall and inner bead depicts environmental structure and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
